同時提高金屬材料的強度和韌性的最有效方法是細(xì)化晶粒，而利用彌散分布的第二相粒子細(xì)化基體組織已成為工業(yè)上常用的強化方法。第二相粒子具有釘扎晶界的能力，對單相多晶材料的晶粒長大有很大的影響，其通過限制晶界的移動性，最終使晶粒停止長生，晶粒達(dá)到極限尺寸。 翻譯： One of the most effective ways to enhance the ambient-temperature mechanical performance, i.e. yield stress as well as plasticity for crystalline metallic materials is to refine their microstructure. A effective way was used widely in industry to get the fine microstructure is realized by dispersing the second-phase particles in the matrix. The second-phase particles act as obstacles to the motion of grain boundaries and thus retard grain growth. Due to their importance in the application of various materials, grain growth in the presence of second-phase particles has been a subject of great interest for many decades. 請高手幫潤色或補充翻譯一段話 ，非常感謝！ |

| The most effective way to enhance the strength and toughness of metallic element is grain refinement. Nowadays refinement of matrix structure by dispersing second-phase particles has been widely used in industry. The second-phase particles can pin grain boundary and have great impact on grain growth. Through constraining the mobility of grain boundary, it can finally make grain stop growing and achieve extreme dimension. |

The most effective way to enhance the strength and toughness of metallic materials is refining grain, and in industry the widely applied way to refining grain is to refine the microstruture of matrix with dispersing the second-phase. Because of the pinning effect of grain boundaries, the second-phase particles have important effect on the growth of grain in single-phase polycrystalline materials by restraining the motion of grain boundaries to stop grain growing and to reach the limited size of grains.
